hi Doug, A follow up question: when I look at the xxx.ocn.y.dat for a cluster where group differences in surface area have been identified the values are all less than 1 (e.g. 0.761374) even though the cluster size is reported as 680 mmsq. does the y value correspond to .76 mmsq average area for that subject in that cluster or does the y value in the context of surface area analyses represent something else? (or does it need to be multiplied by some factor?)
Thanks!
